The working principle of medical high pressure syringe


Medical high-pressure syringes usually consist of an injection head holder, a control panel, and a manual switch. The injection head is a device that controls the injection of contrast agent or saline. It can be programmed to complete the inhalation of liquid, discharge of air in the syringe and pipeline, and high-pressure injection.

The injection head also has the prompt function of the current working status, such as preparation completion, fault prompt, and injection status display. The control screen is a human-computer interaction interface, and its main function is to set the injection program, control the injection process, real-time display of the progress of the injection process, injection end report, and real-time pressure curve display during the injection process.

What is the role of medical high-pressure syringes?

1. Cardiovascular Angiography

Because when angiography of the heart and aorta, especially for aortic angiography and retrograde angiography, it is required to inject a large dose of contrast agent in a short time to ensure that the contrast agent is not immediately diluted by blood. In order to obtain high-quality contrast images, in this case, ordinary products cannot do so, and a high-pressure syringe is needed.

2. Contrast-enhanced CT scan

In the early days, CT enhanced scanning was manually pushed, but due to the uneven delivery of the liquid medicine and insufficient boosting force, the effect of angiography was not good, and the high-pressure injector was used in the CT enhanced scanning, which made it easy to operate and punctual delivery* *, and can reduce the amount of contrast agent, so it is useful for medical high-pressure syringes.

3. MR enhanced scan

The application of the MR high-pressure injector can accurately preset the enhancement site, the injection speed, the total amount of contrast agent and the delay time, and the application of the high-pressure injector is helpful for the realization of rapid breath-hold scanning.
